Description

A kind of active head restraint of seat

Technical field

The utility model belongs to the Vehicular occupant apparatus field of operation, transportation class, is specifically related to the headrest on the seat.

Technical background

The high backseat that the vehicle top rade is adjustable, its headrest all is fixedly set in the topmost of the chair back.When the passenger gets when facing upward the lying posture rest, different because of passenger's height, cause most passenger can't use headrest, even this pillow become also that facing upward lies and had a rest the obstacle of discomfort, against former the design's original intention.

Summary of the invention

The purpose of this utility model provides a kind of active head restraint that can make every passenger seat all applicatory, to overcome the deficiency of said fixing headrest.

The technical solution of the utility model is: it is made up of headrest and degree of tightness positioning belt two parts.The two ends of headrest are connected with degree of tightness positioning belt two ends; Rest the head on two head heights, middle part are low, and the front and back that concave is faced upward occipitalia meet the physiologic radian requirement of head and neck to arc.

The utility model has the advantages that:, thereby be fit to passenger's use of various different heights owing to active head restraint can conveniently be located at the arbitrary height of the chair back; Because the front and back that concave is faced upward occipitalia meet the physiologic radian requirement of head and neck to arc, thereby with health role to cervical vertebra; Simultaneously, when the passenger was just sitting, active head restraint also can move down, and made the support pad of waist.And, simple in structure, be easy to making, with low cost.
